Precision Shoulder Screw - Slotted

Shoulder Screws get their name from the extremely tight tolerance shoulder between the head and the threads on the part. The shoulder is held to a +/-0.0005 tolerance. This allows for these parts to act as pivot points, locating points, dowels, guides, and many other uses. As new industries find uses for these high tolerance shoulders, new variations such as low and ultra-low profile heads, or vibration resistant and thread locking patches.
